Fixes a phenomenon in which the image files cannot be transferred using the FTP protocol via USB cable after the Canon EOS 7D camera has established a wireless connection to the Wireless File Transmitter WFT-E5A.

Firmware Version 2.0.5 is for cameras with firmware version 2.0.3. If the camera’s firmware is already Version 2.0.5, it is not necessary to update the firmware. Once the camera is updated to version 2.0.5, it cannot be restored to a previous firmware version.

If it really only fixes the bug listed in the descirpotion, I don't really need it.

If there are hidden changes, I would like to learn about them.

If there are hidden changes that cause compatibility issues with third-party gear I will skip it. See Nikon D5300 and DF issues with Sigma lenses and third-party batteries following Nikon FW-Updates. Those impacts were also not documented. I know, that is Nikon and here we talk Canon ... but still!

I had read about the battery problem with Nikon D5300 camera after the last update..... I think that the messing around with compatability is the reason why Sigma has come out with thier docking station for updating lens firmware.... Personally, I would not buy an expensive third party lens without something similar.

Me too ... it had me all excited for a second.On a different note, here is my theory on some of these updates by the big boys (Canon / Nikon): in my limited experience, sometimes when I updated these kind of "not so significant updates", my Canon and Nikon cameras would suddenly start having trouble with third party lenses and accessories e.g. the usually fine working Sigma or Tamron lens suddenly back/front focuses, or it makes some odd clicking noise when the OS/VC engages etc or accessories such as third party batteries are suddenly not recognized in the camera. So, sometimes I wonder if these are deliberate attempts by the big boys or just an unavoidable technical glitch. Unless one is actually affected by a problem with the WFT-E5A, for those with third party lenses or accessories, it might be worth while to wait and watch.

Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out.

Exactly what i was goign to post.

So now we have to be wary of all canon updates...that just stinks.

The opteka batteries for the Eos M are SOOOOO much better than the canon brands that its just sad. Usability would drop significantly if they implemented a block.
